IMPROVEMENT IN CHURNS.

Specification forming part ofLetters Patent No. 153,763, dated August 4,1874; application filed July 2, 1874.

To all whom it may concern:

Be it known that I, NATHANIEL EWING, of Houston, in the county of Harrisand State of Texas, have invented a new and Improved Churn; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawing, forming a part of this specification, in which I Figure 1 is afront view. Fig. 2 is a top view. Fig. 3 is a detail view.

The invention relates to means whereby the dashers of plunge-churns maybe speedily, conveniently, and accurately adjusted to the quantity ofcream which constitutes the churning at any one time, and also whereby adetachable churn itself may be easily and securely fastened to a framejust previous to the commencement of the churning operation.

These means will first be fully described,

and then pointed out in the claims.

A represents a churn, B, its table or platform, and G Ginwardly-concaved blocks, between which it is held; The inside block, 0,is stationary, while the outside one, C, is hinged at c to turnhorizontally, and open-slotted at 0 On each side, of the slot are thebeveled faces 0 0 against which work the subjacently and correspondinglybeveled shoulders (I d of the cap D, which is pivoted at d in a slot, b,of the platform.

By this construction, the cap D, which is otherwise liable to be jostledout, and has a tendency to allow some play to the hinged block 0, iscaused to hold it rigidly in place, thus rendering the churn immovableduring the churning process.

The rod E, rising from the dasher inside, passes, as usual, through ahole in cover F, and is pivoted between the prongs g g of the yoke G.The latter has two heads, g, between which work the eccentric H, andwhich are connected by the parallel strips g 9 Between these strips andheads is protruded the ordinary crank-shaft I, which is end-threaded,and provided, not far from the protruding end,

with a fixed collar, J. Against this collar bears one side of theeccentric H, which has a radial slot, preferably'but not necessarilyclosed. By moving the slotted eccentric radially its center of motion ismade to approximate more or less to that of the drive-shaft I, accordingas it is intended to raise and depress the dasher more or less.

In order to fasten the eccentric disk at any point of adjustment,Iemploy a tube, K, whose inner end bears against the disk, while itsouter end is provided with a flange, k. L is a Washer, which may or maynot be used, and M a thumb-nut, which works on the end of shaft I. Byscrewing and pressing the inner end of nut against the washer, ordirectly against the outer end of tube K, the disk is eifectuallyclamped to the shaft at any desired point of eccentricity to the latter.

As in all farming establishments, and families who make their ownbutter, the quantity of cream made will vary at different seasons andoften from temporary causes, it is very important that the throw of thedasher should be susceptible of a quick and easy adjustment.

Having thus described my invention, what I claim as new is 1. Thecombination, with platform B having slot 1), the inwardly-,concavedstationary block (J, and the correspondingly-concaved block 0 hinged atc to turn horizontally, slotted at c, and having beveled faces 0 c ofthe cap D having subjacently-beveled shoulders 01 d, and pivotedat d inthe platform, as and for the purpose described.

2. The yoke Gr composed of prongs g g, between which is pivoted thedasher-rod, heads g g, and parallel strips g 1 and the radiallyslotteddisk H, in combination with flanged tube K k, nut M, and end-threadeddrive-shaft I, as and for the purpose specified.

- NATHANIEL EWING.
